[michaelkhabarov]

Set url: 'http://localhost' option to jsdom-global. This fix SecurityError: localStorage is not available for opaque origins in mocha tests caused of jsdom (jsdom/jsdom#2304).

Is there any workaround for this problem in the meantime when using mocha?

You can create a setup file and require it in test:unit script in package.json

mocha.setup.js:

require('jsdom-global')(undefined, { pretendToBeVisual: true, url: 'http://localhost' })

package.json:

"test:unit": "vue-cli-service test:unit --require ./mocha.setup.js"
